Nicotine Replacement Therapy (NRT) is a medically approved way to help people quit smoking by providing a controlled dose of nicotine without the harmful chemicals found in tobacco. It comes in various forms, including patches, gum, lozenges, inhalers, and nasal sprays, allowing users to manage cravings and withdrawal symptoms effectively. The goal of NRT is to reduce the physical dependence on nicotine while supporting behavioral changes necessary for long-term cessation. By gradually decreasing nicotine intake, individuals can improve their chances of quitting smoking successfully and enhance their overall health.
